-Routine Description:
- Service routine for RealTimeClockInstance->GetTime
-
-Arguments:
-
- Time - A pointer to storage that will receive a snapshot of the current time.
-
- Capabilities - A pointer to storage that will receive the capabilities of the real time clock
- in the platform. This includes the real time clock's resolution and accuracy.
- All reported device capabilities are rounded up. This is an OPTIONAL argument.
-
-Returns:
-
- EFI_SUCEESS - The underlying GetSystemTime call occurred and returned
- Note that in the NT32 emulation, the GetSystemTime call has no return value
- thus you will always receive a EFI_SUCCESS on this.
